Description
Technical field
The present invention relates to electric connector and its technical field of sealing technology, particularly a kind of cable seal and cable seal connection
Device.
Background technology
In electric vehicle charging multi-plug cable component, the multicore electricity for the electric wire composition that cable differs greatly for multiply diameter
Cable, such as Fig. 1（a）It is shown, there are the problem of sheath outer diameter tolerance and cylindricity tolerance are big, and not full grade is filled in inside, lead
It sends a telegraph between cable and connector there are sealing problem, to be made cable folding, distortion, cable by external force effect during permanent use
Inevitably there are opposite displacements between connector.For this problem, the prior art is generally solved using cable seal ring, is such as schemed
1（b）Shown cable seal ring uses solid structure, it will usually since environmental factor makes cable and sealing ring aging, deformation
Deng so as to be difficult to meet for a long time using seal request.
In the prior art, the cable connector of electric vehicle alternating-current charging, connector shell are entirety or separate structure：Such as
Fig. 2（a）Shown application publication number is the charge connector of 104685727 A of CN, and connector shell is by multiple shell divides
The split structure of body docking composition；Such as Fig. 2（b）It is illustrated that the cable that shell is the symmetrical separate structure in cable seal position
Connector, including shell 01 and cable protective net 04, shell circumference is equipped with body seal slot 02, for housing Housing seal member,
Realize the sealing of shell 01 when being locked to facet；Shell 01 sets cable seal slot close to the inside portion of cable 05, for housing
Cable rubbery seal 03；When then connecting and lock between split shell 01, the cable rubbery seal 03 in cable seal slot
It will be compressed and be connected, then the position of sealing element is kept by cable protective net 04, so as to fulfill the sealing of product requirement.
Cross-sectional view such as Fig. 1 when the sealing ring of the prior art is applied in cable connector assembly（c）It is shown, wherein D1
For cable cover(ing) overall diameter, D2 is the diameter of bore of connector shell, and A1 is the semidiameter of D2 and D1, and A2 is the horizontal stroke of sealing ring
Sectional dimension, X are the eccentricity of D1 and D2, are influenced by assembling product and use.Specifically, A1=（D2-D1±X）/2；For product
Meet the condition of expected waterproof, sealing ring should meet Suitable compression rate range（If static seal recommends 15% ~ 30%, dynamic sealing is recommended
6% ~ 20%, compression ratio range is not the main points of this patent, not discusses and determine herein detailed data）, cable sealing ring compression
Rate E, wherein E=（A2-A1）/A2 x100%；Due to size A2, D1 and D2, there are tolerance, the cable sealing ring pressures of dimension limit
Shrinkage Emin=［ A2min-（D2max-D1min+X）/ 2 ］/A2min * 100%, Emax=［ A2max-（D2min-D1max-
X）/ 2 ］/A2max * 100%；In general, sealing ring for elastic rubber material it is molded, the dimensional tolerance of sectional dimension A2 and
Cylindricity tolerance △A2（It is not shown in figure）It is smaller；It is molded that connector shell is generally synthetic resin, sealing hole dimension D 2
Dimensional tolerance and cylindricity tolerance △D2It is smaller, therefore the sealing waterproof of connector shell is easily able to require；Cable is given birth to due to it
Production. art limits, the dimensional tolerance of sheath overall diameter D1 and cylindricity tolerance △D1Electricity larger, that particularly stranded conductor is twisted
Cable, tolerance bigger, the sealing waterproof for leading to cable are difficult.Therefore, the prior art has the following problems：
Problem 1：As (△D1+△D2) change it is larger when, need increase sealing ring A2 values, connector shell can be caused accordingly to increase；
Problem 2：Sealing ring compression ratio E can cause assembling product difficulty to increase, and production efficiency reduces；Also sealing ring is caused to damage
It is bad, make seal failure risk.
Invention content
It is an object of the present invention to provide a kind of cable seal and cable seal connectors, can solve multicore cable
Sheath outer diameter tolerance and cylindricity tolerance sealing problem caused greatly are particularly suitable for the smaller multicore cable of diameter variation
